Spin squeezing generated by the anisotropic central spin model
Lei Shao, Libin Fu
Spin squeezing, as a crucial quantum resource, plays a pivotal role in quantum metrology, enabling us to achieve high-precision parameter estimation schemes. Here we investigate th…
Verification of colorable hypergraph states with stabilizer test
Hong Tao, Xiaoqian Zhang, Lei Shao +1
Many-body quantum states, as a matter of fact, are extremely essential to solve certain mathematical problems or simulate quantum systems in measurement-based quantum computation.…
Optimal quantum phase estimation in an atomic gyroscope based on Bose-Hubbard model
Lei Shao, Weiyao Li, Xiaoguang Wang
We investigate the optimal quantum state for an atomic gyroscope based on a three-site Bose-Hubbard model. In previous studies, various states such as the uncorrelated state, the B…
Charging of quantum batteries with general harmonic power
Jie Chen, Liyao Zhan, Lei Shao +3
We analyse the charging process of quantum batteries with general harmonic power. To describe the charge efficiency, we introduce the charge saturation and the charging power, and…
